A customer needs a fibered alum recoat on his bitumen roof. It us a duplex, roof is sound(i recoat it every few years). The neighbor sharing the roof overlaid TPO. The TPO is not bonding along the seperating joint and laps onto “my” roof. Will fibered fabric bedded in elastomeric cement(“muck n’ tape”) be sufficient? Am hesitant to add fasteners…more holes = more leak culprits. A 3-5 yr workmanship guarranttee maybe acceptable at this budget. I normally use Henry 552 cement.
